Manchester City won their third Premier League title, and fifth English top-flight title overall, with five games to spare.[4] The team broke numerous Premier League records over the course of the season, including: most points (100), most wins (32), most away wins (16), most goals (106), most consecutive league wins (18), highest goal difference (+79), most passes in a game (903), fewest minutes behind in matches (153 minutes) and biggest winning points margin (19).[5][6] All three promoted clubs avoided relegation for the first time since the 2011–12 campaign, and for only the third time in Premier League history.

From this season on, a three-man panel consisting of a former player, a former manager and a former match official will independently review video evidence on the Monday after games. Any player whom the three-man panel unanimously decide has caused an opponent to be sent off or has won a penalty as a result of deceiving the referee by simulation will be charged by the Football Association with "Successful Deception of a Match Official" which carries a penalty of suspension for two matches. Everton striker Oumar Niasse became the first Premier League player to be punished under the new rule.[10]

Manchester City were confirmed as Premier League champions following Manchester United's 0–1 defeat at home to West Bromwich Albion in the 33rd round. Manchester City had started the Premier League season with an away win over Brighton & Hove Albion in August. After a draw against Everton, Manchester City won eighteen games in a row. During this time they secured first position and held it for the remainder of the season. On 7 April, Manchester City lost to Manchester United in the local derby, in which a win would have secured their position as champions. The following week, Manchester United lost to bottom club West Bromwich Albion, and Manchester City defeated Tottenham. These results ensured Manchester City held an unassailable lead with five games left.[11]

Defending champions Chelsea started the season badly, losing their opening game to Burnley 2–3; the first time the holders were defeated at home in their first match. A win at one of the title favourites, Tottenham, in their second game seemed to get their defence back on track, but results in September, including losing 0–1 to Manchester City, left them six points behind the leaders in fourth place. They failed to show the consistency of the previous season, and finished in fifth place. Manchester United started the season strongly winning their first three games without conceding a goal and led the table until mid-September. However, following convincing wins against Liverpool (5–0), Watford (6–0) and Crystal Palace (5–0), Manchester City went top of the league in September and remained there for the rest of the season. During the campaign Manchester City broke and set several new club and English football records. They established national records in consecutive away (11) and overall (20) victories in all competitions; set a new English record for consecutive league wins (18); equalled the Premier League record for consecutive away league wins (11) and set club records by achieving 28 consecutive games unbeaten in all competitions; 30 consecutive games unbeaten in the league; 20 consecutive home wins in all competitions; and winning 14 away games in a season.[12][13][14][15] They won their fifth English league title, and completed their second league and League Cup double in four years.

Arsenal had a poor season, finishing sixth overall. Long-serving manager Arsène Wenger announced his departure from the club on 20 April 2018.[16] Their final home game was an emphatic 5–0 defeat of Burnley which guaranteed qualification to the group stage of the Europa League.[17]

Stoke City were the first team to be relegated to the EFL Championship when they lost 1–2 to Crystal Palace in their penultimate game. Although Stoke were only three points from safety with one game remaining, fellow strugglers Swansea and Southampton still had to play each other, meaning that Stoke would be unable to catch both of those teams and finish fourth from bottom.[20] The game between Swansea and Southampton ended in a 1–0 away win for Southampton, which also meant that despite a five game unbeaten run, West Bromwich Albion became the second team to be relegated to the Championship on 8 May 2018.[21] Following their 1–2 defeat at the hands of Stoke on the final matchday, Swansea City were also relegated.[22]

Twenty teams competed in the league – the top seventeen teams from the previous season and the three teams promoted from the Championship. The promoted teams were Newcastle United, Brighton & Hove Albion and Huddersfield Town, returning to the top flight after an absence of one, thirty-four and forty-five years respectively. This was also both Brighton & Hove Albion and Huddersfield Town's first season in the Premier League. They replaced Hull City, Middlesbrough (both teams relegated after a season's presence) and Sunderland (relegated after ten years in the top flight).

^ abSince the winners of the 2017–18 FA Cup (Chelsea) and the winners of the 2017–18 EFL Cup (Manchester City) both qualified for European competition based on their league positions, the berths awarded to the 5th-placed team (Europa League group stage) and the League Cup winners (Europa League second qualifying round) were passed down the league.
